Matrix Switch
Description
The main function of the NCS6415 is to switch 8 video input
sources to the 6 outputs.

Figure 1. Block Diagram
The main function of the NCS6415 is to switch 8 video
input sources to the 6 outputs.
Each output can be switched to only one of the inputs,
whereas any single input may be connected to several
outputs. The lowest level of each signal is aligned on each
input (bottom of sync pulse for CVBS or Black Level for
RGB signals).
The nominal gain between any input and output is 6 dB.
For Chroma signals, the alignment is switched off by
forcing, with an external 5‘ VDC resistor bridge on the input.
Each input can be used as a normal input or as a Chroma
input (with external resistor bridge). All the switching
possibilities are changed through the I2C bus.
The switches configuration is defined by words of 16 bits:
one word of 16 bits for each output channel.
So, 6 words of 16 bits are necessary to determine the
starting configuration upon power−on (power supply: 0 to
10 V). But a new configuration needs only the words of the
changed output channels. Driving a 75 W load requires an
external transistor.

USING A SECOND NCS6415
The programming input pin (PROG) allows two
NCS6415 circuits to operate in parallel and to select them
independently through the I2C bus by modifying the address
byte. Consequently, the switching capabilities are doubled,
or IC1 and IC2 can be cascaded (see Figure 7).

TYPICAL APPLICATION DIAGRAM
NCS6415 is suited for single supply system, running on
broadcast studio quality signals. The layout is not as critical
a single +10 V supply. The high quality of the output stage
to the design and it can be easily realized on a single sided
and excellent linearity provides video signal comparable to
board.
